Sigma 50mm F1.4 DG DN Art vs Tamron 35-150mm F/2-2.8 Di III VXD

The bottom line

The Tamron 35-150mm F/2-2.8 Di III VXD is a zoom (35-150mm) and the Sigma 50mm F1.4 DG DN Art is a 50mm prime. The zoom gives you framing flexibility from one lens; the prime trades that for a fixed focal length that's usually brighter (f/1.4 vs f/2) and lighter to carry. Choose flexibility or a fast single focal length.

  • You want more light and background blur — f/1.4 is faster than f/2, better for low light and subject separation.
  • You prefer a fast, compact single focal length — a 50mm prime over a zoom.
  • You value portability — at 665g (1.47 lb) it's lighter than the 1165g (2.57 lb) alternative for travel and all-day carry.
